This invention relates to a hair waving machine and has for its object to provide an apparatus of this type which will be capable of imparting a wave to hair in a rapid, ef-

ficient and safe manner.

Another object is to provide a machine which will be adaptable for imparting a plurality of individual waves at one time and which will employ substantially or identically the same amount of heat for each wave.

Another object is to provide a machine of the type described which will employ steam as a heating medium and which will render the steam available to the hair undergoing treatment in such manner as to eliminate the probability of burning, singeing or otherwise injuring either the hair or the scalp from which the hair arises.

More specifically, it is the object of this invention to provide a hair curling machine which will direct a supply of steam for heating locks of hair entrapped in a plurality of individual curling irons, to arrange the irons in series in order that a steam circuit may be established therethrough, and to provide means for controlling both the rate of steam generation and the rate of supply to the irons.

A further object is to provide curling irons which will accept a wide lock of hair,-that is, a lock which, if viewed sectionally at the scalp, will have a pronounced elongated shape, said irons being adaptable to impart any desirable tightness to the lock during placement therein, and which will permit a definite rolling and tightening thereof over the entire length of the look.

A further object of the invention is to provide means for generating steam in accord with the requirements of the curling irons, to provide the requisite number of regulators therefor, and to provide a further means for instantaneously relieving the irons of a steam supply in case of emergency.

Other objects and advantages either directly related or indirectly implied will become hereinafter more fully apparent as reference is had to the accompanying drawings wherein our invention is illustrated, and in which g e is a vertical ection h g y improved hair curling machine having my improved curling irons diagrammatically il-- lustrated as being connected thereto. said section taken along the line 1-1 of Fig. 2,

Fig. 13 is a vertical section taken along the line 1313 of Fig. 12, and

Fig. 14 is a partial frontal view of the cabinet shown in Figs. 12 and 13. p

In the views the character 1 refers generally to a cabinet in or near the bottom of which is supported a flash boiler 2 heated by a burner 3. Extending into the boiler 2 is a water supply line. 4 which leads from a reservoir 5 by way of reversely seated check valves 6 between which is placed a pump 7. The handle 8 for this pump extends outwardly from the cabinet so that an operator may control the feeding of water and hence determine the rate of steam generation by the boiler 2. steam line leads eut ardly fr m the boiler 2 to a union 9 where it divides into a plurality of lines 10 which extend outwardly from the cabinet at the points 11. It will be noted that these lines 10 are carried outwardly of the cabinet near the top thereof in order to receive the benefit of the waste heat from the generator to prevent condensation therein.

From the points 11 the lines are connected to a plurality of curling irons assemblies to be hereinafter more fully described and to return lines 12 which lead from these irons into the cabinet at points close to the supply tank 5. The length of these lines outwardly of the cabinet 1 together with their exposure to the water in the tank 5 provides a cooling action which promotes condensation and hence induces a flowof steam through the curling irons. An even and continuous flow through each of the irons in series is assured because stoppage at any point stops the flow through all irons in seriestherewith so that the pressure in the line immediately rises unduly and the degree of rise is shown on an indicator 13 located in a wall of the cabinet said indicator being visible to the operator stationed at the pump handle. The supply of steam from the boiler may be instantaneously arrested or reduced in volume by the actuation of a handle 14, outwardly of the cabinet, which controls a valve 15 in the line 10. A safety relief valve 16 is provided on the boiler for this or any other emergency.

In Figs. 12, 13 and 14 the parts corresponding to similar parts in Figs. 1 and 2 are primed. The salient feature of the form of these figures is the illustration of the convenient employment of the boiler pressure to eflect complete circulation. Thus the feed line 4 may connect directly into a municipal water system, and the final tank 33 may become simply a drainage means from which the water collecting therein is evaporated by the waste heat from the burner 3 or other- Wise disposed of. Since pressure from the boiler is solely relied upon in this instance for circulation of steam through the several curling irons, the return line 12' may enter the cabinet 1 at points close to the points 11 as shown in Fig. 14. Y

The curling iron assembly is composed of a curling iron and its casing as shown in Figs. 3 and 4 in which the iron is composed of a hollow tubular member 17 having a large cross-section at each end and gradually diminishing in size towards its mid-section, and a clamp 18 which ensnares the end of a lock of hair against the tubular member 17 in order that the hair may be rolled about the iron. This shape together with the pivoted clamp permits the wrapping of a wide lock of hair spirally therearound as distinguished from the helical wrapping sometimes seen and which has been found to be inferior to the spiral method. 1

At each end of the tubular member 17 bearings 19 are provided for reception by resilient journals 20 provided at each end of a casing 20. The casing 20 is preferably insulated with a resilient packing 21 which extends outwardly of the walls so that when the casing is assembled about the iron a packing is formed along the edges 21. Thus when the end clamps 22 are swung into locking engagement the casing constitutes a steam tight compartment.

The tubular member 17 is provided with perforations 23 which vent steam into the easing 20 from the line 10, the line 10 being connected into the tubular member 17 by means of a frictional or other desirable type of connection. The outlet end of the tubular member 17 is connected to a flexible connection 24 which is a part of the line 10 and which leads into another assembly, finally emptying into the return line 12.

A pad 25 having a slot 26 therein and upstanding side-walls 27 constitutes a scalp protector. A lock of hair is drawn through the slot 26 whereupon a clamp 28 is locked therearound. This clamp is of metal having a resilient covering over each of its jaws, the covering extending outwardly to form wings 29 for reception by the ledge 27 around the pad 25, the portion 30 adjacent the metal jaws being formed as a cradle to receive the casing 20. A wrench 31 is provided to rotate the iron on its bearings by means of a pin 32 of a bayonet joint 32 in order that the casing may be drawn tightly against the cradle 30. \Vhere the curling irons are in series in each of two steam lines-the application of the irons to the hair of the head at each side of the latter is facilitated and many parts and connections dispensed with, suchas are present when the irons are in parallel. It is an aim ofour invention to secure such advantage by adequate control of the heating means so as to secure the proper heating of the individual iron notwithstanding they are in series.
